I’ve finally completed the assembly of my winding machine—now upgraded with precision CNC parts from JLCCNC! 🎉

Assembly with JLCCNC Parts

As mentioned in this blog post, we’re preparing to sell the winding machine as a kit and want to share our shipping approach with you.

Shipping Only Core Parts​

Because the full machine is heavy and international shipping is expensive, our plan is to include only the essential/custom parts in the kit. Customers would then source common or bulky components locally and print/machine structural parts themselves using the provided STL files.

I’ve decided to sell the BLDC motor winding machine as a kit for people who want to build one themselves. This project began when one of my expensive gimbal motors failed due to a wire break. Later, it evolved into a solution for the lack of high-quality gimbal motors on the market—by producing and selling motors myself.

Open source software has changed the world—but can the same model work for hardware? I'm not so sure.

I rely on amazing open source software every day: Ubuntu, KiCad, FreeCAD, and many others. These tools empower independent developers and makers like me to build and create without corporate gatekeepers. So naturally, I love the idea of open source.

But when it comes to hardware, I hesitate.

During COVID, many desk workers experienced the comfort of working from home—something that physical laborers couldn't enjoy. Ironically, those same desk jobs are now the first to be automated by AI. Today, intelligent tasks like writing grant applications or generating reports can be done for free with large language models, while automating simple physical tasks like cleaning still requires buying a $300+ robot vacuum.

I've been working on building a motor winding machine for over two months. The primary reason I started this project was that I wanted to create a gimbal motor for robotics projects. However, I found that gimbal motors are not as available and affordable as drone motors.

Gimbal motors are great for robotics projects. They are smooth, precise, and powerful at low speeds.

I like the Arduino framework because it's easy to use and has a lot of libraries. However, I have been using STM32 for a while now, and I have to say it's awesome. Here are some of the reasons why I like STM32:

High school robotics competitions are popular and have been around for decades. Even a hobbyist can build a robotic arm with a 3D printer. However, why is it so difficult to build a useful robotic arm?
